2009-05-12T19:59:00.000-07:00

Hi,

Last time i seem in the forum, he ask a question how to make XML file from the object collection or array with LINQ.Because of LINQ has a excellent support to XML.

Here Code snippet.

To this i just take simple example.

C#.NET

Private void MakeXMlFile()
{

Employee[] employees = new[] {
new Employee {FirstName = "Joe", LastName = "Rattz", Email="Test@hotmail.com",Phone="12345343"
},
new Employee {FirstName = "Ewan", LastName = "Buckingham",
Email="Test2@hotmail.com",Phone="122232345343"}};

XElement xBookParticipants =
new XElement("Employees",
employees.Select(p =>
new XElement("Employee",
new XElement("FirstName", p.FirstName),
new XElement("LastName", p.LastName),new XElement("Email",p.Email),
new XElement("Phone",p.Phone))));
Console.WriteLine(employees);

}

VB.NET

Class Employee
Public FirstName As String
Public LastName As String
Public Email As String
Public Phone As String
End Class

private sub MakeXML()

Dim employees As Employee() = New () {New Employee(), New Employee()}

Dim xBookParticipants As New XElement("Employees", employees.[Select](Function(p) New XElement("Employee", New XElement("FirstName", p.FirstName), New XElement("LastName", p.LastName), New XElement("Email", p.Email), New XElement("Phone", p.Phone))))

How to write Gridview data to XML file in .NET

2009-04-29T11:24:00.000-07:00

Hi,

One my colleague asked me yesterday , how we could save the Grid View Data to XML File, just i think come to this point and share with you.

Just Read data from the Grid View to DataSet, then we need write that dataset ti XML file.

C#:

DataSet ds = new DataSet("TestDataset");
DataTable dt = new DataTable("TestDataTable");
dt.Columns.Add("Id", System.Type.GetType("System.String"));
ds.Tables.Add(dt);
//Add any number columns here
for (int count = 0; count < GridView1.Rows.Count; count++)
{
DataRow dr = dt.NewRow();
dr[0] = GridView1.Rows[count].Cells[0].Text;
//you can add values to all columns in datatable
dt.Rows.Add(dr);
}
ds.Tables[0].WriteXml("d:\\test2.xml");

VB.NET:

Dim ds As New DataSet("TestDataset")
Dim dt As New DataTable("TestDataTable")
dt.Columns.Add("Id", System.Type.[GetType]("System.String"))
ds.Tables.Add(dt)
'Add any number columns here
For count As Integer = 0 To GridView1.Rows.Count - 1
Dim dr As DataRow = dt.NewRow()
dr(0) = GridView1.Rows(count).Cells(0).Text
'you can add values to all columns in datatable
dt.Rows.Add(dr)
Next
ds.Tables(0).WriteXml("d:\test2.xml")

That's it

Thank you

How to pass the value when call exe in another application in .NET

2009-04-29T11:14:00.000-07:00

Hi Guys,

I seem in forums lot's of the developer asking how to pass the arguments when they call exe within the another application in.NET. is quite easy.

Code

C#:

Process process = new Process();
process.StartInfo = new ProcessStartInfo("abc.exe");
process.StartInfo.Arguments = "folderpath "; // if you need suply multiple arguments you need put space "A B"
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
process.Start();

VB.NET:

Dim process As New Process()
process.StartInfo = New ProcessStartInfo("abc.exe")
process.StartInfo.Arguments = "folderpath "
' if you need suply multiple arguments you need put space "A B"
process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
process.Start()

2009-04-24T10:20:00.000-07:00

Hi Guys,

Following code support to search types file with in the Directory including sub directories also.

public class FileSearch
{
ArrayList _extensions;
bool _recursive;
public ArrayList SearchExtensions
{
get { return _extensions; }
}
public bool Recursive
{
get { return _recursive; }
set { _recursive = value; }
}
public FileSearch()
{
_extensions = ArrayList.Synchronized(new ArrayList());
_recursive = true;
}
public FileInfo[] Search(string path)
{
DirectoryInfo root = new DirectoryInfo(path);
ArrayList subFiles = new ArrayList();
foreach (FileInfo file in root.GetFiles())
{
if (_extensions.Contains(file.Extension))
{
subFiles.Add(file);
}
}
if (_recursive)
{
foreach (DirectoryInfo directory in root.GetDirectories())
{
subFiles.AddRange(Search(directory.FullName));
}
}
return (FileInfo[])subFiles.ToArray(typeof(FileInfo));
}
}

How to Use:

FileSearch fileser = new FileSearch();
fileser.Recursive = true;
fileser.SearchExtensions.Add(".rar");
FileInfo[] dirRar = fileser.Search("D:\\test");

Hi,

This code snippet to help build windows form grid Under the Windows Presentation Foundation with Winodws Host Object.and also it C# code.

Note:Before add this code you need add Windows Host Object WPF Windows under the any parent control, and also rename to windowsFormsHostDetail.

internal void WindowsFormGridInit()
{
System.Windows.Forms.DataGridViewTextBoxColumn Column2;
System.Windows.Forms.DataGridViewCheckBoxColumn Column3;
System.Windows.Forms.DataGridViewCheckBoxColumn Column4;
